An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-20895 exists.\n\nAffected product: Vmware Vcenter Server. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2023-20895/ (Markdown: https://insights.sbomify.com/CVE-2023-20895/index.md)","id":"CVE-2023-20895","markdown":"https://insights.sbomify.com/CVE-2023-20895/index.md","name":"CVE-2023-20895","record":{"aliases":["GHSA-88h4-vqxf-pwjm"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["security_bypass","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VMware vCenter Server","requires_auth":"none","summary":"A memory corruption flaw in VMware vCenter Server allows network attackers to bypass authentication and potentially execute code.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"vcenter_server","vendor":"vmware"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"The VMware vCenter Server contains a memory corruption vulnerability in the implementation of the DCERPC protocol. A malicious actor with network access to vCenter Server may trigger a memory corruption vulnerability which may bypass authentication.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":null,"headline":"Memory corruption in VMware Cloud Foundation (vCenter Server)","id":"CVE-2023-20895","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"vmware:vcenter_server","products":["vmware:vcenter_server"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":2,"next":{"headline":"Denial of service in VMware Cloud Foundation (vCenter Server)","id":"CVE-2023-20896"},"packages":[],"prev":{"headline":"Memory corruption in VMware Cloud Foundation (vCenter Server)","id":"CVE-2023-20894"},"products":["VMware Cloud Foundation (vCenter Server)","VMware vCenter Server (vCenter Server)"],"published":"2023-06-22","related":[{"cvss_score":9.8,"headline":"Broadcom VMware vCenter Path Traversal","id":"CVE-2026-59310","kev_date_added":"2026-08-18","published":"2026-07-30"},{"cvss_score":9.8,"headline":"VMware vCenter Server Out-of-Bounds Write","id":"CVE-2023-34048","kev_date_added":"2024-01-22","published":"2023-10-25"},{"cvss_score":9.8,"headline":"VMware vCenter Server Information Disclosure","id":"CVE-2020-3952","kev_date_added":"2021-11-03","published":"2020-04-10"},{"cvss_score":5.3,"headline":"VMware vCenter Server Improper Access Control","id":"CVE-2021-22017","kev_date_added":"2022-01-10","published":"2021-09-23"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2015-2342","kev_date_added":null,"published":"2015-10-12"},{"cvss_score":9.8,"headline":"vCenter authentication-bypass vulnerability","id":"CVE-2026-59309","kev_date_added":null,"published":"2026-07-30"},{"cvss_score":9.8,"headline":"Memory corruption in VMware Cloud Foundation","id":"CVE-2024-37080","kev_date_added":null,"published":"2024-06-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["VMware"]},"summary":"A memory corruption flaw in VMware vCenter Server allows network attackers to bypass authentication and potentially execute code.","url":"https://insights.sbomify.com/CVE-2023-20895/"}
